Dear Mr. Zimmer: Pursuant to the National Traffic and Motor Vehicle Safety Act of 1966 15 USC 1381 et. seq., the National Highway Safety Bureau issued Federal Motor Vehicle Safety Standard 109 (FMVSS-109). This standard set forth strength, bead unseating, endurance, high speed and labeling requirements for passenger car tires manufactured on or after January 1, 1968, for use on cars manufactured after 1948. This standard does not apply to other types of tires. A copy of FMVSS-109 is enclosed. A manufacturer self-certifies that the tire meets the minimum requirements of the standard by molding the symbol 'DOT' into the tire. Subsequent identification of the tire as a 'second' would not negate the certification.; The National Highway Safety Bureau is currently testing many bran /size tires to verify their conformance to Federal Motor Vehicle Safety Standard No. 109. The tests are conducted at independent laboratories under contract to the Government. Results of these tests are released to the public in a monthly summary.; The test results does not reflect the Bureau's position on the matter Favorable test results should not be interpreted as necessarily establishing that a specific tire is in conformity with the standard, similarly, unfavorable test results should not be interpreted as establishing nonconformance.; Copies of individual test reports con be obtained, for a fee of $3.0 per publication, from the Clearinghouse for Federal Scientific and Technical Information, Springfield, Virginia 22151. Should sufficient data be left remaining on the tire in question for proper identification you may wish to avail yourself of this service.; There is an organization which could possibly furnish you with the nam of an individual capable of analyzing the causes of tire failures. Their name and address is: America Council of Independent Laboratories, Incorporated. 1714 West Capitol Avenue, Houston, Texas 77007.; I trust this information will be useful to you, and I appreciate thi opportunity to be of assistance.; Sincerely, Francis Armstrong, Director, Office of Compliance, Moto Vehicle Programs;
